South Galaxy G1 product review

South Galaxy G1 RTK GNSS receiver is equipped with a 220 channel Trimble BD970 or 555 channel Novatel 729 GNSS board. In combination with an RTK Subscription this receiver is capable of providing centimetre accuracy in real time. Because The South Galaxy G1 supports GPS, Glonass, Galileo and Beidou satellite constellations it is capable of achieving this centimetre accuracy in tough conditions. Down below you can find which frequencies it supports. This receiver is also equipped with Trimble Everest multipath rejection technology. This features helps to detect low quality satellite signals to increase the overall stability. It allows you to get an RTK fix in the most inaccessible locations with poor satellite coverage. You can upgrade this receiver with a Tilt sensor to increase accessibility in more difficult places.

Using the South G1 as a rover

When using this device in a rover configuration you may need the following accessories besides the receiver itself

• RTK Correction service. To achieve centimetre accuracy your receiver will need RTCM correction data so it can calculate your exact position. Without an RTK provider your receiver won’t be able achieve a 1-2 centimetre accuracy.
• Surveying software. Your receiver provides you with the coordinates you need but you still need surveying software in order to process this information. Which software you need depends on your needs. We recommend keeping it simple and don’t pay for things you don’t need. Having that said, if you do have to do complicated surveying work make sure you get the right software. Some recommended options are Carlson, Aplitop and FieldGenius. If you need help, feel free to contact us by phone or via the chat below!
• Data collector. You might need a tablet or controller to run your software on. The type of tablet depends on which software you have chosen as some are Android based and some are Windows.
• Bracket and Holders. These are used to connect your tablet to your surveying pole so the whole set is easier to handle.
• Surveying pole. In order to get the best performance out of your receiver you want to minimise the disturbances around you and give it a clear sight to the satellites above. That why its recommended attaching your receiver on a 2 meter minimum surveying pole. These come in fixed rods and in telescopic rods.

Can the South Galaxy G1 be used in a base rover setup?

When you don’t have access to an  RTK network you might have to setup your own base station in order to receive corrections. These are the accessories you might need besides the receiver itself:

• A second RTK GNSS receiver. preferably from the same brand. If you already have another one, then make sure they run on the same frequency.
• Surveying software. Your receiver provides you with the coordinates you need but you still need surveying software in order to process this information. Which software you need depends on your needs. We recommend keeping it simple and don’t pay for things you don’t need. Having that said, if you do have to do complicated surveying work make sure you get the right software. Some recommended options are Carlson, Aplitop and FieldGenius.

• Tripod and Tribrach. These are needed to setup your base station with the second receiver. The Tripod gives good stability so errors in sudden movements of the base station are avoided.
• External Radio. Most RTK GNSS receiver have an internal UHF radio build in. However, sometimes the power output is not strong enough to give you the workable distance you need and an external radio required. Internal radios can go up to 3 Watts that can work up to 8km. External radios can easily achieve 35 Watt outputs, thereby increasing your working range.
